FLUID-DISCHARGING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 351,453, dated October26, 1886.

' Application filed October 12, 188;). Serial No. 179,623. (No model.) I

To all whom it may concern:

Beit known that I, WILLIAM T. MESSINGER, of Cambridge, county ofMiddlesex, State of Massachusetts, haveinvented an Improvement inFluid-Discharging Apparatus, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

My invention relates to a fluid-discharging apparatus adapted to be usedin connection with water or other pipes or receptacles from which afluidis to be drawn.

Theinvention is embodied in an apparatus consisting, essentially, of avalve chamber containing an inwardly-projecting valve consisting of aflexible disk confined at its edges in a frame provided with guide-armscooperating with the walls of the chamber, the said disk being exposedto the pressure of the fluid in the chamber and seat, and valve movabletoward and from said seat, its movement toward the seat being in thedirection of the outflow of fluid, and a movable faucet, which alsoconstitutes the valve-actuating device and co-operates with the. saidvalve to unseat the latter. When the valve. is unseated by the movementof the faucet, the fluid, which is permitted to flow, passes through thedeliverypassage in the faucet, which thus forms a guide for the saidescaping fluid. As soon as the valve is released or disengaged by themovement of the faucet it is seated by the flow of the fluid, andremains held on its seat by the pressure of the said fluid, andthefaucet maythen be wholly removed from the apparatus, leaving thevalve closed andinacce'ssible, so that the fluid cannot be withdrawn byunauthorized persons.

The invention'consists in various details of construction by which theefficiency and durability of the apparatus is increased.

Figure 1 is a longitudinal section of a fluidcontrolling apparatusembodying this invention, especially adapted for use in connection withwater-pipes, the valve being shown as seated or closed; Fig. 2, alongitudinal section of a modification thereof, intended to be used inconnection with a receptacle for wines or other liquids which it may bedesirable to make inaccessible 'to unauthorized the valve being shown asunseated Fig. 3, a longitudinal section of the persons, or open;

trolling apparatus with the faucet removed, and Figs. 4 and 5 end andside elevations, respectively, of the valve detached.

The apparatus comprises a valve-chamber, (1., adapted to be connected bya coupling-nut, b, with a neck or fitting, c, which may be connectedwith the pipe or receptacle from which the fluid is to be delivered, andwhich closes or forms one end of the valve-chamber a when the latter isconnected therewith, the said fitting 0 having an inlet-opening, 0, tothe said valve-chamber, which is provided with avalveseat, a projectinginward from the end of' the chamber opposite the said fitting, and aguidepassage in said seat for the removable faucet which receives anddischarges the liquid leaving the said valve-chamber.

The flow of fluid from the valve-chamber a is controlled by a valve, (2,shown in this instance as composed of adisk or diaphragm of rubber orother yielding material confined at its edges in a ring or frame, (1,having a shoulder, d (see Fig. 1,) upon which the said disk is fastenedby a nut or cap, (2, provided with openings d, (see Fig. 4,) throughwhich the fluid may pass, so as to press directly upon the diaphragm (l,and thus hold the latter tightly upon the seat a without necessity of 3grinding or packing. The ring (1 is pro vided with a series ofguide-arms, (i which fit loosely within the chamber a, so that the saidvalve can travel freelyback and forth toward and from the seat a. in thesaid chamber, there being a sufficient space between the armsd and theouter wall of the ring d and inner wall of the chamber a for the flow offluid through the said chamber around the valve when the latter isunseated, as shown in Fig. 2. The guide-arms d are also longer than thewidth of the ring d, and thus constitute a stop, limiting the movementof the valve toward the inlet-passage 0., so that it cannot close orobstruct the said passage. The valve d, if acted on only by the fluidflowing into the chamber a from the passage 0, will be moved up to andheld pressed against the seat, thus preventing the escape of fluid fromthevalve chamber and reservoir or source of supply communicatingtherewith through the passage c.

In order to actuate the valve for the purpose of opening the same, andalso to receive and guide or control the fluid which may escape fromthevalve-chamberwhen the valvcis open, the apparatus is provided with afaucet, e, which also constitutes the valve-actuating device, and has asuitable delivery-passage, e, and a portion, 0, adapted to enter andmove longitudinally in the guidepassage in the valve-seat (5. The saidfaucet 0, when pressed inward toward the valve-chamber a, engages thevalve (1 and moves the latter from its seat, so that the fluid may flowinto the portion c of the faucet, which is provided with lateral portsa, through which the fluid passes from the valve-chamber (6 into thedelivery-passage c, as shown by the arrows, Fig. 2, out of which itflows in the usual manner.

The piece or casting forming the chamber a is shown as provided with anexternal extension, a, serving as an additional guide for the faucet c,which moves longitudinally therein. In order to prevent leakage orescape of the fluid around the outside of the faucet 0 when the valve isopened the said faucet may be provided with a yielding washer orpackingring, e, which, when the said faucet is pressed inward, as shownin Fig. 2, comes to a seat around the outer end of the passage in thevalve-seat and prevents the escape of fluid through the said passage,except by passing through the delivery-passage c.

The faucet a may be operated or pressed inward, to open the valve,'inany desired manner. As shown in Fig. 1, it is provided with an operatinghandle or lever, f, having an opening, j, which surrounds the saidfaucet, the said handle or lever being pivoted to the said faucet, asshown at f, and being connected by a link, f with the guide portion a ofthe valve-chamber. Thus by pressing the handle f toward thevalve-chamber the faucet 0 is moved inward, opens the valve, and permitsthe fluid to escape through the ports 6" into the passage e,- and assoon asit is desired to stop the flow of the fluid the handle may bemoved forward or merely released, when the pressure of the fluid will,in most cases, be sufficient to move the valve and faucet both forwarduntil the valve is seated and prevents the further escape of liquid. Theapparatus thus made forms an efficient self-closing faucet forwater-pipes or other similar purposes. the fluid being permitted toescape only as long as the operator holds the valve open.

\Vhile the valve is seated the faucet has no function to perform, andmay be wholly removed from the apparatus, as shown in Fig. 3, and whenthe apparatus is to be used for controlling the flow'of a valuableliquid, or one which it is desirable to protect from unauthorizedpersons,the faucet 6 may be wholly removed from the apparatus andretained in possession of, the person who is authorized to draw thefluid. \Vhen intended to be used in this manner, the handle may berigidly connected with the faucet, as shown at f, Fig. 2, and the lattermay be merely inserted in the extension or guide passage a of the pieceor casting forming the valve-chamber a when it is desired to draw thefluid and removed there from as soon as sufficient fluid is withdrawn.If desired, however, the faucet constructedas shown in Fig. 2 may beretained in connection with the valve-chamber by a couplingnut, fconnected with the guide projection a, and adapted to engage a shoulder,0, upon the said faucet. The guide projection a preferably is providedwith external threads to receive the coupling-nutf, or, if desired, toreceive a protecting-cap, h, as shown in Fig. 3, which may be screwedtightly upon it after the faucet has been removed,'so as to preventtampering with the valve or with the fluid controlled by unauthorizedpersons not provided with a proper faucet. In case the flow or pressureof the fluid should not be suiiicient to seat the valve, a spring may beplaced between the valve and the fitting 0, tending to seat the valve,and an apparatus operating upon the same principle as that described inthe present application, provided with such a spring, will be shown anddescribed in another application for Letters Patent, Serial No. 179,625,filed October 12, 1885.

It will be seenthat the faucet which constitutes the fluid-dischargingand valve-actuating device and its operative mechanism is wholly outsideof the valve-chamber and beyond the valve, so that there are no jointsor passages to work loose and cause leakage, and, furthermore, the valvecannotbe forced against its seat so as to injure the face of the valveor seat, as frequently happens in faucets in which the valve ispositively pressed against its seat by a valve-stem or other actuatingdevice.

I claim 1. In afiuid-discharging apparatus, avalvechamber provided withinlet and outlet openings, and a valve-seat surrounding the saidoutlet-opening and projecting into the valvechamber, combined with avalve working in the said valve-chamber between the inlet and outletopenings thereof, the said valve consisting of a flexible disk andsupportingframe therefor, having guidearms co-opcrating with the wallsof the valve-chamber, the said disk being confined at its edges in theframe and having its entire surface exposed to the pressure of the fluidin the valve-chamber, and a movable faucet working in the outlet-openingof the valve-chamber, bcin g disconnected from the valve, but engagingand unscating the same in its movement toward the valve-chamber,substantially as described.

2. The valve-chamber provided with inlet and outlet openings andavalve-seat surrounding the said outlet-opening and projecting into thevalve-chamber, combined with a valve consisting of a flexible disk andsupportingframe therefor, having guidearms co-operating with the wallsof the chamber, the said disk being confined at its edges in the frameand having its entire surface exposed to the pressure of the fluid inthe valve-chamber, and a movable faucet working in the outlet- Openingof the valve-chamber, disconnected from the valve, but engaging andunseating the same in its movement toward the valvechamber, and a handlelever pivoted upon said faucet and connected by a link with thevalve-chamber, substantially as described.

8. The valve-chamber provided with a valveseat having a guide-passagetherein, and the extension of the said chamber beyond the saidvalve-seat, combined with a valve movable in the said valve-chamber andguided wholly by the walls thereof, and a movable faucet working in thesaid extension and having a projecting portion of smaller diameterworking in the guide-passage in the valve-seat, the said faucet beingdisconnected from said valve and movableindependently thereof, butengaging and unseating the valve in its movementthrough theguide-passage,,the shoulder at the end of the said projecting portion ofthe faucet constituting a stop, limiting the movement of the-faucettoward the valve-chamber, substantially as described.

4. The combination of the main cylindrical valve-chamber a, provided atone end with an inwardly-projecting seat, (1, having a guidepassagetherethrough, and a coupling-piece, a, and couplingnut connecting thechamber therewith, the said coupling-piece forming one end of thechamber and having an inlet thereto, combined with a valve consisting ofa flexible diaphragm and supporting-ring therefor working in the saidvalve-chamber, and the movable faucet 6, working in the guide-passage-of thevalve-seat, disconnected from the said valve and movableindependently thereof, and an operating device connected with saidmovable faucet, substantiallyas set forth.

In testimonylwhereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.
